'2 Claims. (Cl. 215-100) This invention relates to improvements invacuum bottles and similar containers, and provides retaining means formaintaining a bottle in an upright position and also against rollingabout when carried in a tractor, bulldozer, or agricultural implement,to particularly prevent breakage or loss of the vacuum bottle, thebottle being provided with a casing having a permanent magnet forcooperation with a magnetizable wall or floor.

Operators of road building and maintenance equipment and of agriculturalimplements and similar devices usually carry a vacuum bottle of colfeeor other drink with them while operating the implement, storing thebottle in some compartment or recess. Since vacuum bottles are prone tobreak or shatter when subjected to relatively light jars, many arebroken through rolling about the enclosure, or by rolling out of arecess, and my invention assures freedom from breakage through fallingover, rolling about the enclosure or olf the recess or pocket, and istherefore particularly adapted for use with such implements andvehicles.

The objects and advantages of the invention are as follows:

First, to provide a vacuum bottle with a casing having a permanentmagnet incorporated therewith for attachment to a magnetizable wall orthe like for maintaining the bottle in a fixed position against jarringaction.

Second, to provide a vacuum bottle as outlined with a cup provided witha portion of magnetizable material for releasable attachment to thepermanent magnet to provide a support for a hand-held vacuum bottle cupor cap while lunching or drinking.

Third, to provide a permanent magnet with a band to encircle an existingvacuum bottle to which the permanent magnet was not applied duringmanufacture.

In describing the invention reference will be had to the accompanyingdrawings, in which:

Fig. 1 is a front elevation of a vacuum bottle having my inventionapplied thereto, and showing the bottle magnetically secured to anupright wall of magnetizable material.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 shows the vacuum bottle retained against rolling on a floor ofmagnetizable material.

Fig. 4 is a front elevation with the cup or cap removed and supported bythe magnet on the casing.

Fig. 5 is a top plan view of a vacuum bottle with the cup removed, andthe permanent magnet applied through the medium of a spring clip whichsubstantially encircles the casing.

The invention can be applied to the casing of any type of vacuum bottle,either during manufacture, or after manufacture, and is thereforeapplicable to all existing vacuum bottles.

The bottle proper, or filler as it is usually referred to, and indicatedat 11, is housed within the casing 10 with the neck projecting slightlyas indicated at 11. A stopper, not shown is supplied for sealing thebottle.

A combined cap and cup 12 is threaded onto the neck 13 of the casing andprotects the neck of the bottle against damage or breakage.

The invention resides in the application of a permanent magnet 14 to oneside of the casing, and may either be locked or otherwise secured in thesidewall of the casing preferably adjacent to the collar 15,'or may befixed to a resilient clamp 16 as indicated at 17 so that the magnet canbe attached to existing vacuum bottles, this magnet and its attachmentto the casing being the principal feature of the invention. It will benoted that the inner face of the magnet is arcuately formed to conformto the curvature of the casing, while the outer face is provided with aprojecting leg on each, the upper and lower end portions and extendingthroughout the width of the magnet, for spaced cooperation with amagnetizable surface for maximum flow of flux through the magnetizablesurface for a maximum degree of magnetic adhesion.

For increased utility, the combined cap and cup 12 is provided with asection or band of magnetizable material and which consists of a thinportion 18 which terminates in a shoulder 19, the bottom surface 20being suitably rounded, and the edge 21 broken or slightly rounded toeliminate a sharp edge.

It will be noted that the upper leg has a plane top surface 22 and aplane front surface 23, the depth of the intervening surface between thelegs, indicated at 14 in Fig. 3, being equal to or slightly greater thanthe depth of the shoulder 19 on the cup, so that the shoulder will seaton the top surface with the magnetizable band or section 18 magneticallycooperating with the surface 23 for suitably holding the cup in properposition. For removal, the cup is not to be drawn directly away from themagnet, but is to be rotated about the casing until the shoulder leavesthe terminal edge, thus here will be no jerk to cause spillage of thecontents of the cup.

With existing vacuum bottles it is merely necessary to' apply the clamptype shown in Fig. 5 to the bottle, and the ring 18, 19, 20 can also beapplied to the cup either in the form of a spring clamp or pressed on,so that this invention is applicable to all vacuum bottles, eitherduring, or after manufacture.

I claim:

1. In a vacuum bottle or the like having a casing having a side wall anda combined cap and cup, at permanent magnet mounted adjacent the upperend of said side wall, said permanent magnet having a plane top face anda plane from face at right angles to each other, a band of magnetizablematerial mounted at the lower end of said combined cap and cup whenapplied to the bottle as a cap, said band terminating in an annularshoulder for cooperation with said top face with said band cooperativewith said front face for supporting the combined cap and cup when usedas a cup, through magnetic adhesion, with the cup removable throughrolling action about the side wall until the shoulder clears theterminal edge of the top face.

2. In a vacuum bottle having a casing having a side wall having an upperend and a lower end, and a combined cap and cup; a permanent magnetmounted on said side wall adjacent said upper end and having a top face,

"movementofthe'cap along the side wall'until the shoulder passes theterminal edge of the permanent magnet,

'saidprmanent magnetmai'nta'in'ing the vacuum bottle against falling orrolling through magnetic'adhesion to a body of magnetizable material.
